COMPLEX INSTRUMENT FOR SPECIFIC RESISTANCE ELECTRODE MEASURING AND ELECTRO-MAGNETIC DISTANT MEASURING |
摘要 |
FIELD: oil and gas industry. ^ SUBSTANCE: complex instrument includes loaded drilling pipe that consists of the first and the second part separated by isolated gap, and distant-measuring cartridge containing distant measuring scheme that includes power source generating voltage drop at isolated gap, and axle current at drilling column that is returned through geologic bed, it also includes isolated measuring electrode connected to the first part and scheme for specific resistance measuring connected in the course of operation to measuring electrode and distant-measuring scheme. ^ EFFECT: integration of possibilities to measure specific resistance into electro-magnetic distant-measuring instrument and obtaining the data of specific resistance as well as distant measuring. ^ 58 cl, 11 dwg |
